Avaliação de dispositivo oscilométrico de alta definição comparado com o método de pressão invasiva para aferição de pressão arterial sistêmica em cães submetidos a procedimentos anestésicos

Abstract

The measurement of systemic blood pressure (SAP) is complex, since through it is possible to assess myocardial function, vascular bed distensibility, circulatory volume, in addition to peripheral perfusion. Therefore, its analysis is fundamentally and widely used in clinical and surgical routine of small animals. In anesthetic procedures, its use is necessary since blood pressure (PA) can undergo fast and frequent changes as a result of several factors, as well as through it, it is possible to evaluate the response to therapies. PA can be measured indirectly, using oscillometric and Doppler methods, for example, and directly, using invasive blood pressure (gold standard). Some scholars suggest the use of the gold standard for the development of research on different techniques in veterinary medicine, with the intention of seeking more effective and less invasive methods. Given its importance, this study aimed to evaluate the indirect method using the high-definition oscillometer compared to the direct blood pressure assessment method. In this way, 16 healthy mixed-breed dogs were selected to participate in the study. After that, the SAP was be measured and assessment the good agreed between methods.
